Hi Mikhail,

thanks for contacting me and sorry for the late reply :-/

In the end, no changes will be needed in the cmake files I guess, but I
had to override a couple of variables to get it to build:

cmake -DUSE_SYSTEM_ZLIB=YES -DUSE_SYSTEM_PNG=YES -DUSE_SYSTEM_CAIRO=YES
-DCAIRO_LIBRARY_DIRS=/usr/lib/$(DEB_HOST_MULTIARCH)
-DUSE_SYSTEM_PIXMAN=YES -DPIXMAN_INCLUDE_DIRS=/usr/include/pixman-1
-DPIXMAN_LIBRARY_DIRS=/usr/lib/$(DEB_HOST_MULTIARCH)
-DLIBPIXMAN=libpixman-1.so

Some of those are due to different file layout in Debian as we are using
/usr/include/pixman-1 for the pixman header files and the multi-arch
library directory for cairo.

One possibility would be to use pkg-config in cmake for cairo in order
to automatically discover where the cairo headers and library are.

This is usually not recommended, unless the project is only useful to
Debian and nobody else, which is not the case for indigo.

One thing which would really help would be to better version the indigo
library, though maybe you are not concerned about it as upstream.

We assigned "libindigo.so.0d" for now (the d stands for debian), the
question is whether indigo-1.1 is backwards-compatible with indigo-1.0?
I check the library symbols and it was not very clear.  If there is no
backward compatibility, we will have to bump the library name to
libindigo.so.1d.



Best regards,

Michael
