Is there any reason, why including just this header is not enough? Maybe some
required definitions missing?
CMake checks includes by compiling a simple program that does nothing. If
compilation fails, the header is assumed not to exist. Those CMake flags can
be helpful in diagnosing the issue:
--debug-trycompile = Do not delete the try_compile build tree.
Only useful on one try_compile at a time.
--debug-output = Put cmake in a debug mode.
--trace = Put cmake in trace mode.

Subject: [CMake] Check header file woos
All,
I am trying to use CheckIncludeFiles for header file check. I know the file I
want to check is located at /usr/include/lustre, so I supplied the following:
include(CheckIncludeFiles)
check_include_files(lustre/lustre_user.h HAVE_LUSTRE_USER_H)
And it report can't find. Then I tried to be explicit about it
set(CMAKE_REQUIRED_INCLUDES /usr/include/lustre)
Still no avail. If I check any other header file in that directory, say
sys/io.h, it will work as expected. I am puzzled ... anything I missed?
Thanks
