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 aCsource 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 useCMAKE_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- 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 the CheckIncludeFiles module to check for multiple headers
at once. See the CheckIncludeFileCXX module to check for headers
using the CXX language.
