# On Windows, static libraries are using "foo.lib" naming.
# On Unix, they are in the form of "libfoo.a"
# On Windows, "foo.lib" can also the definition of symbols in a foo.dll.
# So you can link to "foo.lib", whatever you are doing static or dynamic linking and you are good.
# However, meson is always creating static library as "libfoo.a"
# 'to avoid a potential name clash with shared libraries which also generate import libraries with a lib suffix.' [1]
# On top of that, qmake is replacing all `-lfoo` in LIBS by `foo.lib` (on Windows).
# So at the end, we try to link with `foo.lib` but we have `libfoo.a`
# Solution could be :
# - Rename `libfoo.a` to `foo.lib`, but it would mean modify deps libraries on the FS
# - Don't use LIBS and directly set QMAKE_LFLAGS but we would have to handle different command line option format
#   between g++/clang and msvc
# - Update meson build system of each projet to explicitly set the library naming.
# - Replace `-lfoo` with absolute path to static library. This is what meson is doing internally and what
#   we are doing here
#
# Any `-lfoo` is replace with absolute path to static library (`libfoo.a`) if we found one.
# Else, it is keep unchanged.
