Update the logic added by commitef41d49812(Fix implicit include directory extraction for adaptive relative paths, 2019-04-08, v3.14.2~5^2) to account for the new `try_compile` work directory used for the ABI check since commit2edf0fc6d7(Modules: Use new keyword-dispatched try_compile signature, 2022-09-13, v3.25.0-rc1~144^2). Paths relative to the work directory will now have one more `../` in them, so update the test data to match. Fixes: #24279
This directory contains sample input files for the implicit include directories, and link info parsers for testing. For each configuration there is one ".input" file and matching ".output" files in ParseImplicitIncludeInfo/results and ParseImplicitLinkInfo/results. To generate ".input" files for a system, create a temporary build directory and chdir to it. Then run cmake pointing to this directory. The CMakeLists.txt file here will generate ".input" files in your build directory. The default set of languages is C and CXX. This can be changed with -DLANGUAGES=language_list. For example: -DLANGUAGES=Fortran will generate Fortran parser input. The ".output" files should be generated by hand from the input files. The test will compare the parser output to the manually generated ".output" file. The two should match. For compilers that support "-nostdinc"-like flags, you can generate a test for this with a command like: cmake -DUNAME=netbsd_nostdinc \ -DCMAKE_C_FLAGS=-nostdinc -DCMAKE_CXX_FLAGS=-nostdinc . Here is an example for testing the XL compiler with both -I and nostdinc: env CC=xlc CXX=xlC cmake -DUNAME=linux_nostdinc_i \ -DCMAKE_C_FLAGS='-qnostdinc -I/tmp/ii/test_c' \ -DCMAKE_CXX_FLAGS='-qnostdinc -I/tmp/ii/test_c -I/tmp/ii/test_cxx' .
