[Cbc] Fwd: CMake version of Cbc

[Sumit K. Nath]

Hello Stefan
I am aware that it can be built under Linux. What I asked in the previous
mail was how to modify the CMake script so that it builds under linux. If
you take a look in the CMake subfolder, you will find a
Win32CompilesFlag.cmake. How can we write a similar script (say
LinuxCompilesFlag.cmake)? I am interested in the defines that go with it.
If that is available, then this can be used to compile the project under
Linux as well. I have a lurking suspicion that most of the defines for
MinGW can be reused for Linux (in addition to -fPIC for 64-but builds).
However, I would rather have confirmation from someone who has built it
under Linux.

Thank you for the information about LAPACK.

How can we build share libraries for the sub projects?

Best regards
Sumit
