What happened?
When building with MPI disabled and vernier loaded from the software stack, the build fails with a cryptic error:
[ 30%] Built target vernier
[ 32%] Linking CXX executable test_profiler
$PWD/build/tests/unit_tests/c++/test_profiler: symbol lookup error: $PWD/build/tests/unit_tests/c++/test_profiler: undefined symbol: _Z8MPI_InitPiPPPc
CMake Error at /data/apps/spack/releases/2025.11.19/install/linux-rhel9-zen2/gcc-12.2.0/cmake-3.30.5-ktdsgm4ll462blorzs6imncxit2ddt5k/share/cmake-3.30/Modules/GoogleTestAddTests.cmake:112 (message):
Error running test executable.
Path: '$PWD/build/tests/unit_tests/c++/test_profiler'
Working directory: '$PWD/build/tests/unit_tests/c++'
Result: 127
Output:
This happens because $LDFLAGS also contains a reference to vernier and the build system is picking this up rather than the version that should be being tested. This should probably trigger an error.
