Some c++ programs(in fact, almost every for me) can't be configured using makepkg.

However, if I mannually configure them(cd into /src and run ./configure or cmake for some programs)

It runs smoothly. Then I comment all the line before "make" in PKGBUILD, run makepkg, makepkg works well and generate a perfect tar.xz file. So it's just the problem: configure under makepkg can't detect
proper c++ complier. It won't affect my computer because I can mannually configure them, but it's awful that I have to stop half-way in the process of makepkg. I can list 3 packages below:
Dolphin-emu-svn Desmume-svn fbterm
I just wonder why.

Additional info:
* package version(s)
* config and/or log files etc.
