The Make install target does not install a libllhttp.pc pkg-config file

[apteryks]

As can be seen at

llhttp/Makefile

Line 90 in ee51043

install: build/libllhttp.a build/libllhttp.so

the provided Make build system does not template nor install the libllhttp.pc file, while the CMake build system does. It'd be nice if the Make-based build system also did.
