CheckIncludeFiles¶
Provides a macro to check if a list of one or more header files can be included together.
-
CHECK_INCLUDE_FILES¶ CHECK_INCLUDE_FILES("<includes>" <variable> [LANGUAGE <language>])
Check if the given
<includes>list may be included together in a source file and store the result in an internal cache entry named<variable>. Specify the<includes>argument as a ;-list of header file names.If
LANGUAGEis set, the specified compiler will be used to perform the check. Acceptable values areCandCXX. If not set, the C compiler will be used if enabled. If the C compiler is not enabled, the C++ compiler will be used if enabled.
The following variables may be set before calling this macro to modify the way the check is run:
CMAKE_REQUIRED_FLAGSstring of compile command line flags.
CMAKE_REQUIRED_DEFINITIONSa ;-list of macros to define (-DFOO=bar).
CMAKE_REQUIRED_INCLUDESa ;-list of header search paths to pass to the compiler.
CMAKE_REQUIRED_LINK_OPTIONSa ;-list of options to add to the link command.
CMAKE_REQUIRED_LIBRARIESa ;-list of libraries to add to the link command. See policy
CMP0075.CMAKE_REQUIRED_QUIETexecute quietly without messages.
See modules CheckIncludeFile and CheckIncludeFileCXX
to check for a single header file in C or CXX languages.
