These tests are performed with an installed GDAL library. The test_pkg-config.sh script checks that pkg-config on *nix platforms can discover the correct compilation and linking options to build C and C++ applications. The test_cmake.sh script tests building with C and C++ applications with CMake.

To run these tests, use the test script with the install prefix as the first argument, for example if GDAL was configured with --prefix=/tmp/gdal (or -DCMAKE_INSTALL_PREFIX=/usr/local):

./autotest/postinstall/test_pkg-config.sh /tmp/gdal

the prefix is used to set both PKG_CONFIG_PATH and LD_LIBRARY_PATH (or DYLD_LIBRARY_PATH) environment variables during testing.

If the GDAL library was built as a static library, append --static to disable tests for shared libraries.
