The test_build_cmake_library_psram_workaround verifies that the
mfix-esp32-psram-cache-issue flag is applied to all compile commands in
compile_commands.json when CONFIG_SPIRAM_CACHE_WORKAROUND=y. Although
the import_lib does not need the esp_psram component, this test does. To
avoid adding the esp_psram dependency to the import_lib, disable
MINIMAL_BUILD for this test by explicitly setting the COMPONENTS
variable.
