platform.targets

<?xml version="1.0" encoding="utf-8" ?>
<!--
Include this file at the end of a csproj file (just before the
include of Microsoft.CSharp.targets) to add system-specific defines
for conditional compilation.
Example: libpalaso/SIL.Core.Tests/SIL.Core.Tests.csproj

These constants will be defined:
SYSTEM_UNIX - should be compiled on Linux and Mac
SYSTEM_MAC - should only be compiled on Mac (e.g. Unit Tests specific to Mac)
SYSTEM_LINUX - should only be compiled on Linux

In csproj file:
<Include Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />
<Include Project="..\build\platform.targets" />

To use in C# code:
#if SYSTEM_MAC
/* code that should only be compiled on Mac */
#endif
