When CMake BUILD_SHARED_LIBS=ON is set (e.g. Gentoo Linux CMake default), the current build will:

• Build new DFU file_parsers library as shared
• Install only blisp binary without the also required file_parsers DSO

Therefore, the binary is not usable.

With BUILD_SHARED_LIBS=OFF (regular default e.g. for manual builds), no error to be noticed.

Reason is that blisp/src/file_parsers/CMakeLists.txt does not declare any library type (https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html).

• Either, in case of shared library which is intended to be used also as public export, the built/needed DSO (plus possible public header files) would need to be installed.
• Or, more along the likely intention of f1b93a1: This internal library should be always built explicitly as STATIC.
