CheckIncludeFile¶
Provides a macro to check if a header file can be included in C.
- 
CHECK_INCLUDE_FILE¶
- CHECK_INCLUDE_FILE(<include> <variable> [<flags>]) - Check if the given - <include>file may be included in a- Csource file and store the result in an internal cache entry named- <variable>. The optional third argument may be used to add compilation flags to the check (or use- CMAKE_REQUIRED_FLAGSbelow).
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
- a ;-list of macros to define (-DFOO=bar).
- CMAKE_REQUIRED_INCLUDES
- a ;-list of header search paths to pass to the compiler.
- CMAKE_REQUIRED_LINK_OPTIONS
- a ;-list of options to add to the link command.
- CMAKE_REQUIRED_LIBRARIES
- a ;-list of libraries to add to the link
command. See policy CMP0075.
- CMAKE_REQUIRED_QUIET
- execute quietly without messages.
See the CheckIncludeFiles module to check for multiple headers
at once.  See the CheckIncludeFileCXX module to check for headers
using the CXX language.
