Looking for a 'cmake clean' command to clear up cmake. to clean up cmake files. It triggers a complete configure run and this will rebuilt all targets which.
Cmake Configure File Cleaning
Generate a file with CMake and add it as an executable. I use configure_file to produce the script but. After that no clean-up is performed on the file. You should configure the file to > ${CMAKE. custom generator command rather than CONFIGURE_FILE. 'cmake' seemed to. MAKE_CLEAN_FILES ${CMAKE. Information on the cmake program (makefile generator), which is used to make (compile) the software. See also configure for a simpler script interface for common. Alan W.

If the <input> file is modified the build system will re-run CMake to re-configure the file and generate the build system again.
How to use CMake to configure your projects with deal. IIcmake is controlled by input files that by convention are. CMake. Lists. txt, listing both configuration commands. This page presents some CMake.
How clean generated build system files. Hi, All, Is there any way to clean the generated build system files, like vs project files, make files, it might be ok if.
Lists. txt examples for. A detailed description of the. II project configuration is given in the. II CMake Read. Me.). Simple CMake. Lists.
In this section, we start out with a minimal CMake. Lists. txt. based on the DEAL_II_SETUP_TARGET macro. This method gives. Here is a full example. CMAKE_MINIMUM_REQUIRED(VERSION 2.
FIND_PACKAGE(deal. II 8. 5. 0 REQUIRED. HINTS ${DEAL_II_DIR} ./ ././ $ENV{DEAL_II_DIR}.
DEAL_II_INITIALIZE_CACHED_VARIABLES(). PROJECT(myproject). ADD_EXECUTABLE(mycode mycode. DEAL_II_SETUP_TARGET(mycode).
The first line of this code makes sure that a sufficiently high. CMake is installed. II, therefore it is safe to use this. Next, we find our deal. II installation with the help of the. FIND_PACKAGE command.
In this case requiring at least. The HINTS are a list of directories where the. II is likely to be found. First, the location.
CMake variable DEAL_II_DIR is. After that, we check whether we are in a subdirectory (first. II installation and otherwise use the.
DEAL_II_DIR. If all of these hints fail. The list after. HINTS can be changed according to your preferences. After finding the deal. II project, we fetch a set of cached variables. DEAL_II_INITIALIZE_CACHED_VARIABLES macro.
You. can inspect these for instance with ccmake. Every CMake. Lists. Finally, the last two lines define the executable that is to be produced.
The DEAL_II_SETUP_TARGET macro will set up necessary include. Adding multiple executable targets. In order to specify multiple executable targets, simply repeat. CMake. Lists. txt. ADD_EXECUTABLE(mycode.
DEAL_II_SETUP_TARGET(mycode. ADD_EXECUTABLE(mycode. DEAL_II_SETUP_TARGET(mycode. If the list gets longer, consider using. Adding libraries and common source files.
Adding a library is as simple as adding an executable target. We. specify the library name and then have to tell cmake that the. The code in the simple file below the. ADD_LIBRARY(mylib libsrc. DEAL_II_SETUP_TARGET(mylib).
ADD_EXECUTABLE(mycode mycode. DEAL_II_SETUP_TARGET(mycode). TARGET_LINK_LIBRARIES(mycode mylib).
When you have multiple targets. Accordingly. a loop becomes even more. If you only have a single file or few files with common source. ADD_EXECUTABLE(mycode mycode. DEAL_II_SETUP_TARGET(mycode). ADD_EXECUTABLE(mycode. DEAL_II_SETUP_TARGET(mycode.
You should be aware though that in this case common. If you want to avoid this and.
OBJECT "library". ADD_LIBRARY(common OBJECT common.
DEAL_II_SETUP_TARGET(common). ADD_EXECUTABLE(mycode mycode. TARGET_OBJECTS: common> ). DEAL_II_SETUP_TARGET(mycode). ADD_EXECUTABLE(mycode. TARGET_OBJECTS: common> ).
DEAL_II_SETUP_TARGET(mycode. This will compile common. Switching build types The build type is controlled via the variable. CMAKE_BUILD_TYPE. If it is set to Debug. CMake. Lists. txt. II library. Contrary Release will build in optimized.
II. You can set. CMAKE_BUILD_TYPE with the help of ccmake or via. DCMAKE_BUILD_TYPE="Debug" . DCMAKE_BUILD_TYPE="Release" . Alternatively, you can specify custom targets to switch the build type and. ADD_CUSTOM_TARGET(debug. COMMAND ${CMAKE_COMMAND} - DCMAKE_BUILD_TYPE=Debug ${CMAKE_SOURCE_DIR}.
COMMAND ${CMAKE_COMMAND} - -build ${CMAKE_BINARY_DIR} - -target all. COMMENT "Switch CMAKE_BUILD_TYPE to Debug". ADD_CUSTOM_TARGET(release. COMMAND ${CMAKE_COMMAND} - DCMAKE_BUILD_TYPE=Release ${CMAKE_SOURCE_DIR}. COMMAND ${CMAKE_COMMAND} - -build ${CMAKE_BINARY_DIR} - -target all. COMMENT "Switch CMAKE_BUILD_TYPE to Release".
With that, switching the build type and compiling the project can be done. Adding a "run" target If you wish to have a "run" target for make, like in the deal.
II. tutorial, specify one this way (obviously, a single "run" target can only. ADD_CUSTOM_TARGET(run COMMAND mycode. COMMENT "Run with ${CMAKE_BUILD_TYPE} configuration". Advanced CMake. Lists.
This section covers some advanced topics for a user. CMake. Lists. txt file. Source directory layout. For complex projects it is desirable to organize source code and header. Assume the following project structure with a. In this case the top level CMake. Lists. txt file may be.
CMake. Lists. txt. CMAKE_MINIMUM_REQUIRED(VERSION 2. FIND_PACKAGE(deal. II 8. 5. 0 REQUIRED). DEAL_II_INITIALIZE_CACHED_VARIABLES().
PROJECT(myproject). ADD_SUBDIRECTORY(mylib). ADD_SUBDIRECTORY(mycode). The ADD_SUBDIRECTORY statement will include the CMake. Lists. txt. file in the specified subdirectory. In our case. # mylib/CMake. Lists. txt. INCLUDE_DIRECTORIES(include).
ADD_LIBRARY(mylib. DEAL_II_SETUP_TARGET(mylib). We have to add the directory include for the header files to. INCLUDE_DIRECTORIES.
The corresponding configuration file for the executable looks. CMake. Lists. txt. INCLUDE_DIRECTORIES(. CMAKE_SOURCE_DIR}/mylib/include. ADD_EXECUTABLE(mycode source/mycode. DEAL_II_SETUP_TARGET(mycode).
TARGET_LINK_LIBRARIES(mycode mylib). Please note that CMake. Lists. txt files have directory scope. Any manipulation of properties and variables have only effect in the.
ADD_SUBDIRECTORY. The level above will not be affected. Therefore, we have to specify the include directories for "mylib" again in. CMAKE_SOURCE_DIR}/mylib/include. CMake defines the following variables for access to important directories. CMAKE_SOURCE_DIR. CMake. Lists. txt file).
CMAKE_BINARY_DIR. CMAKE_CURRENT_SOURCE_DIR.
CMake. Lists. txt file (top level or included via ADD_SUBDIRECTORY). CMAKE_CURRENT_BINARY_DIR. CMAKE_CURRENT_SOURCE_DIR. Control statements. Control statements in CMake take the following form. IF(< expression> ).
IF(< expression. ELSEIF(< expression.
Please note the (somehow uncommon) empty, opening and closing brackets. ELSE() and ENDIF(). Important examples are. IF(${variable}). - the body will be evaluated if the variable "variable" is defined and. TRUE, ON, YES (modulo case insensitivity).
IF(variable MATCHES < regular expression> ). IF("${variable}" STREQUAL "foobar"). Note that. "${variable}" will be replaced by the content of the (string). An expression can be negated by prefixing NOT. IF(NOT < expression> ).
Loops are implemented with the help of WHILE and. FOR statements. The former takes the same. IF statement. WHILE(< expression> ).
Given a variable list containing a list, the individual. FOREACH. FOREACH(element ${list}).
Note: It is also possible to specify the list directly. FOREACH(element foo bar baz).
The variable element will iterate through foo, bar and baz. File globs. A very common task is to pick up a list of source files from a. You can either manage a list of source files in.
CMake. Lists. txt by hand, e. The following example will pick up every source file under. SOURCE_DIR/sources/ and add it to an executable. FILE(GLOB sources ${CMAKE_SOURCE_DIR}/source/*. ADD_EXECUTABLE(mycode ${sources}). Please be aware of one caveat of this approach: Due to the fact that. CMake is a build system generator the resulting build configuration.
So, after adding a new. CMake. Lists. txt file or to run. DEAL_II_SETUP_TARGET revisited. The DEAL_II_SETUP_TARGET macro is responsible for setting up. II. It will append the. INCLUDE_DIRECTORIES property with the location of the.
II include directories, and append the properties. COMPILE_FLAGS, COMPILE_DEFINITIONS and. LINK_FLAGS by their respective values from the deal. II. configuration (depending on build type and available debug and/or. Except in the case of an object library, the specified target will also. II (and its transitive link interface) as.
Optionally, the DEAL_II_SETUP_TARGET macro takes an. DEBUG, or RELEASE, after. If the parameter is omitted, the correct choice is deduced. DEBUG taking precedence in. Debug. Release as build type). Note: The flags that are added with DEAL_II_SETUP_TARGET to. This means they take precedence over all flags defined via.
CMAKE_CXX_FLAGS, etc., or as a directory. If you wish to modify flags or preprocessor definitions set up.
DEAL_II_SETUP_TARGET modify on of the following. IIConfig. cmake for. DEAL_II_CXX_FLAGS. DEAL_II_CXX_FLAGS_DEBUG. DEAL_II_CXX_FLAGS_RELEASE.
DEAL_II_LINKER_FLAGS. DEAL_II_LINKER_FLAGS_DEBUG. DEAL_II_LINKER_FLAGS_RELEASE.
DEAL_II_USER_DEFINITIONS. DEAL_II_USER_DEFINITIONS_DEBUG. DEAL_II_USER_DEFINITIONS_RELEASE. DEAL_II_INITIALIZE_CACHED_VARIABLES revisited.
The DEAL_II_INITIALIZE_CACHED_VARIABLES macro is responsible. FIND_PACKAGE(deal. II 8. 5. 0 REQUIRED). DEAL_II_INITIALIZE_CACHED_VARIABLES(). PROJECT(myproject).
The macro will set an uninitialized CMAKE_BUILD_TYPE variable. Debug (or Release if the debug library is not. If CMAKE_BUILD_TYPE is specified it will. II. installation (i.
Debug. Release, or Debug. Release). Furthermore, this macro sets the C++ compiler to the one used for compiling. II library. The variables will CMAKE_CXX_FLAGS. CMAKE_CXX_FLAGS_DEBUG, and. CMAKE_CXX_FLAGS_RELEASE will be initialized with the empty. Note: If you wish to override the flags and definitions set by the. DEAL_II_SETUP_TARGET macro you have to override the.
DEAL_II_* variable instead. See the. documentation of DEAL_II_SETUP_TARGET.
Customizing include directories and compile definitions. You can specify custom include directories and compile definitions prior to. CMake. documentation for further details). INCLUDE_DIRECTORIES(include.
