[CMake] Filenames becomes too big on windows (VS10)

[Martin Nielsen]

Hi All

 

I'm curently facing an issue with filenames becoming too big with the
Visual Studio 10 generator. Doing the compilation of our source code I
get the following errors:

 

"C:\bs-vs2010\synergy-main-winnt-x86-vs10\build\install\no_log\output\no
_log\Synergy.sln" (default target) (1) ->

ack_bluestack_dmlib.vcxproj]

 

I figured that the tool combines the path of the project with the
relative path of the filename located in the project file resulting in
this filename:

 

C:\bs-vs2010\synergy-main-winnt-x86-vs10\build\install\no_log\output\no_
log\bt\profile_managers\core_stack\common\bluestack\dmlib\..\..\..\..\..
\..\..\..\bt\profile_managers\core_stack\common\bluestack\dmlib\dmlib_hc
i_ulp_read_advertising_channel_tx_power_req.c

 

I assume the failure is due to the 260 bytes filename length limitation
within Windows.

 

Would it be possible to direct CMake to use absolute filenames in the
project files instead of the relative path? 

 

Or could this be caused by something else?

 

Med venlig hilsen / Best Regards
