Thanks - looks promising!  I tried with Ninja generator from a VS2008
command prompt.  But I ran into some issues with paths being converted to
relative paths.  A sample test case is attached.  Build it with the Ninja
generator.

I also tried VS2008 generator directly.  That seems to work without error.

The Ninja problem seems to be due to this:

>From build.ninja:

build subdir\ManTest.exe: C_EXECUTABLE_LINKER__ManTest
subdir\CMakeFiles\ManTest.dir\Hello.c.obj | subdir\DPIAware.manifest
  MANIFESTS = DPIAware.manifest
  PRE_LINK = cd .

Corresponding rule:

rule C_EXECUTABLE_LINKER__ManTest
  command = cmd.exe /C "$PRE_LINK &&
C:\Users\JamesJ\AppData\Local\Temp\cmake-build\bin\cmake.exe -E vs_link_exe
--intdir=$OBJECT_DIR --manifests $MANIFESTS --
C:\PROGRA~2\MICROS~1.0\VC\bin\link.exe <snip> && $POST_BUILD"

So the problem is the current directory when linking is going to be root
CMAKE_BINARY_DIR, and the relative path "DPIAware.manifest" will attempt to
be used, which of course isn't there as it needs to look in
"subdir\DPIAware.manifest".

This leads to this error:

DPIAware.manifest : general error c1010070: Failed to load and parse the
manifest. The system cannot find the file specified.

Best regards,

James Johnston
