create split-branch of BuildTools
copy over pkg-config setup macros from BSPsplit branch
copy over also one change to AC_FINALIZE
new macro AC_COIN_HAS_MODULE_FALLBACK to find packages in a non-pkg-config build by reading a ...-uninstalled.pc file
add cludge to handle different usual locations for project libraries
fix for case where COIN_HAS_MODULE_FALLBACK is called without having called COIN_HAS_MODULE before; set ADDLIBS only if required is not 0
fix to setting PROJECT_LIBS
integrate fallback closer into AC_COIN_HAS_MODULE
need to quote argument
fix blas and lapack scripts; add conditional and subst for pkg-config
fix: print result if no fallback provided
setup pkg-config search path in COIN_HAS_PKGCONFIG and AC_SUBST it
update docu
merge split branch rev. 1543 into trunk
directory may not yet exists if it is configured after the current project
do not set FLIBS to -link  /NODEFAULTLIB:libc.lib, since it seem to be not necessary with VS >= 8 and breaks builds where linker flags are reordered at the linkline (or where someone does not take special care that  gets to the end
Precursor; adding macro for doxygen in preparation for later changes.
New scripts for generating stable versions. Significantly different
architecture; see the BuildTools posting 100602. set_externals is modified to
conform to the new architecture. Be careful!
Whoops. Make commit_new_stable generic and safe by default.
append required packages to the beginning of its list, so that projects which have many depending on them end at the end of the list, hopefully giving a working order of linker flags in a static build; fix bug in COIN_HAS_MODULE_LAPACK
