fix: add enable_language() calls at library level

massonal · fpistm · commit a06ddd7fc386 · 2022-12-20T14:52:47.000+01:00
ASM not being enabled when `external_library()` is called
triggered an error where CMAKE_ASM_COMPILE_OBJECT was undefined.
This commit fixes that by adding the calls to enable_language()
earlier in the config process.
