Method 2 was not suitable cause our team was not interested in passing command line arguments to CMake. CMAKECOMMANDLINE extra command line flags to pass to cmake NOEXTERNALINSTALL skip installation of external project ).an optional third argument is the CFlags to add to the compile line or you can use CMAKEREQUIREDFLAGS. adddefinitions adds definition that is fixed at time when cmake (not make) is executed.Im not sure I understand the question, but Perhaps you could use an additional macro for providing command-line C compiler flags, e.g. The cmake executable is the CMake commandline interface. It may be used to configure projects in scripts.Some CMake generators support a toolset specification to tell the native build system how to choose a compiler. 1 CMake time: CMake is running processing CMakeLists.txt 2 Build time: the build tool runs and invokes (at least) the compiler.It has commands which are documented from within CMake: cmake --help- command-list | wc -l 96 cmake --help-command addexecutable I want to have a precompiler symbol with the compiler arguments or command line.
But be aware, that CMAKECXXFLAGS variable contains only flags set by user. If you wish whole set of compile flags, use target property COMPILEFLAGS. CmakeCXXflags:string.

Some systems, like Windows, do not need this flag. The variable CMAKECFLAGS only affects the C compiler, but you are compiling C code. Adding the flag to CMAKEEXELINKERFLAGS is redundant.Variables passed from the command line (such as CMAKEBUILDTYPEDebug) are cached by CMake and thus re-used in CMAKECFLAGS CMAKEREQUIREDFLAGS string of compile command line flags CMAKEREQUIREDDEFINITIONS list of Use this to add KDE kconfig compiler files to your application cmake CFLAGS CXXFLAGS modification.

To create an executable binary, you use the addexecutable() command, i.e. CMake will then take care of adding the proper compiler flags for you.CMake will pass the latter one to the compiler command line directly so it will link against the library. Most of the time. If the library does not exist, the end result is a cryptic linker error. Checks C compiler for support of cflag.

The flag to be used to add a library search path to a compiler.These compiler drivers support a command-line argument to specify the target to cross- compile for. This variable may only be set in a toolchain file specified by the Cmaketoolchainfile variable.
