[GRASS-dev] where is GRASS looking for these dependencies?

The --with-x is AFAIK not used in G7.x (not sure if this applies to
Mac OSX, too).

For the others, as a start, see:

grep opengl aclocal.m4 configure.in
configure.in:LOC_ARG_WITH(opengl, OpenGL)
configure.in:LOC_ARG_WITH_INC(opengl, OpenGL)
configure.in:LOC_ARG_WITH_LIB(opengl, OpenGL)
configure.in:LOC_ARG_WITH_FRAMEWORK(opengl, OpenGL)
configure.in:AC_MSG_RESULT("$with_opengl")
configure.in:case "$with_opengl" in
configure.in:        AC_MSG_ERROR([*** Valid arguments for
--with-opengl= are yes,no,x11,aqua,windows.])
configure.in:LOC_CHECK_INC_PATH(opengl,OpenGL,OPENGLINC)
configure.in:LOC_CHECK_LIB_PATH(opengl,OpenGL,OPENGL_LIB_PATH)
configure.in:LOC_CHECK_FRAMEWORK_PATH(opengl,OpenGL,OPENGLPATH)
configure.in:LOC_CHECK_INC_PATH(opengl,OpenGL,OPENGLINC)
configure.in:LOC_CHECK_LIB_PATH(opengl,OpenGL,OPENGL_LIB_PATH)
configure.in:LOC_CHECK_LINK(opengl32,[#include
<GL/gl.h>],[glEnd();],OpenGL,$OPENGL_LIB_PATH,OPENGLLIB)

grep cxx aclocal.m4 configure.in
configure.in:LOC_ARG_WITH(cxx, C++)
configure.in:    PDAL_CPPFLAGS=`"$PDAL_CONFIG" --cxxflags`
configure.in:LOC_CHECK_USE(cxx,C++,USE_CXX)

etc..
