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 LANGUAGE is set, the specified compiler will be used to perform the
check. Acceptable values are C and CXX. 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_FLAGS- string of compile command line flags
CMAKE_REQUIRED_DEFINITIONS- list of macros to define (-DFOO=bar)
CMAKE_REQUIRED_INCLUDES- list of include directories
CMAKE_REQUIRED_LIBRARIES- A list of libraries to link. See policy
CMP0075. CMAKE_REQUIRED_QUIET- execute quietly without messages
See modules CheckIncludeFile and CheckIncludeFileCXX
to check for a single header file in C or CXX languages.
