Configure Error: "Vorbis >= 1.3.0 required!" (MSYS2)

[MrM21632]

I'm experiencing an issue trying to compile vorbis-tools 1.4.0 on the latest version of MSYS2. I'm passing --with-ogg and --with-vorbis flags to the configure script, as I'm first building libogg and libvorbis separately and then using those library builds to build vorbis-tools. It seems to recognize libogg and libvorbis when configuring, but it then gives this error:

checking for OGG... no
checking for Ogg... yes
checking for oggpack_writealign... yes
checking for VORBIS... no
checking for ov_read_filter... no
checking for library containing cos... none required
checking for Vorbis... yes
checking whether OV_ECTL_COUPLING_SET is declared... no
configure: error: Vorbis >= 1.3.0 required !

What's really strange is that this only occurs if there isn't already an installation of libogg and libvorbis available in the include and library paths that GCC is using.

I think the problem I'm experiencing here is that, when doing the check for OV_ECTL_COUPLING_SET (and possibly others), it doesn't take the --with-ogg and --with-vorbis flags into account.

Any thoughts on what else could be causing the problem?

I'm facing the same issue when building on a linux distro without pkg-config, I have the same error message when running
./configure --with-ogg=/opt --with-vorbis=/opt --prefix=/opt
(both libogg and libvorbis are installed into /opt)

I think I found the root cause in the build scripts, looking at config.log:

configure:18902: checking whether OV_ECTL_COUPLING_SET is declared
configure:18902: gcc -c -O2 -Wall -ffast-math -fsigned-char -g -O2  conftest.c >&5
conftest.c:98:30: fatal error: vorbis/vorbisenc.h: No such file or directory

Notice on the command line there is no include option -I so the compile cannot find the headers it looks for.
Instead, a few statementes above, I can see:

configure:18791: checking for Vorbis
configure:18826: gcc -o conftest -O2 -Wall -ffast-math -fsigned-char -g -O2 -I/opt/include -I/opt/include   conftest.c  -L/opt/lib -lvorbis -lm  -L/opt/lib -logg >&5

this command line provides the compiler the search path for the headers.

I see this issue was fixed with latest commits.
