How do I write a cygport file for two different configurations in the same cygport package

How do I write a cygport file for two different configurations in the same cygport package

[Åke Rehnman]

Hello all,

I was going to update the libftdi1 package which in addition to the 
regular ftdi library contains python bindings. Unfortunately the cmake 
CMakeLists only builds python 3 bindings for this library unless 
explicitly passed some magic variables on the command line. However both 
python 2 and python 3 bindings cannot be built in one go.

So the question is how do I write a cygport file to first compile the 
libraries with python 3 then reconfigure (run cmake again with new 
parameters) and build the python 2 bindings?

Any ideas?

this is the solution implemented to build fftw3
3 times with different parameters.
I will use something similar for postgresql that has the same
problem of your libftdi1.

src_compile() {
         cd ${S}
         cygautoreconf

         mkdir -p ${B}/float
         cd ${B}/float
         CYGCONF_SOURCE=${S} cygconf \
                 --enable-float \
                 --enable-threads \
                 --enable-shared --disable-static \
                 --enable-openmp \
                 --enable-sse -enable-avx \
                 --with-windows-f77-mangling
         cygmake

         mkdir -p ${B}/long
         cd ${B}/long
         CYGCONF_SOURCE=${S} cygconf \
                 --enable-threads \
                 --enable-shared --disable-static \
                 --enable-openmp \
                 --enable-sse2 -enable-avx \
                 --with-windows-f77-mangling
         cygmake

         mkdir -p ${B}/double
         cd ${B}/double
         CYGCONF_SOURCE=${S} cygconf \
                 --enable-long-double \
                 --enable-threads \
                 --enable-shared --disable-static \
                 --enable-openmp \
                 --with-windows-f77-mangling
         cygmake

}

src_test() {
         for precision in float long double
         do
                 cd ${B}/${precision}/tests
                 cygtest
         done
}

src_install() {
         for precision in float long double
         do
                 cd ${B}/${precision}
                 cyginstall
         done
..
