every time vcxproj contains: Import Condition="'$(CpuOnlyBuild)'=='false'" convert fails

[lahavy]

My sln is configurable using .prop files.

Every time a project use one of the variables convert fails

here is the verbose output:

3.188063 25> INFO : Parsing... line 379 node Import attrib {'Condition': "'$(CpuOnlyBuild)'=='false'", 'Project': '$(VCTargetsPath)\BuildCustomizations\CUDA $(CudaVersion).targets'}
