[vtk-developers] VTK formula in homebrew: TK_INTERNAL_PATH

[Samuel John]

A follow up information (and still not a solution - just awork-around)

At first, I thought this is a cmake related bug but I think it is cause by the .cmake files vtk 5.10 ships.
I have to add these two pathes manually to prevent vtk from mixing the headers in the MacOSX10.7.sdk and VTK/build/Utilities/TclTk/internals.
This happens only on Macs without the Command Line Tools.

Anyone an idea how to teach VTK to always using the Framework? "-DCMAKE_FIND_FRAMEWORK=FIRST" did not work.


Setting 

> CMAKE_FRAMEWORK_PATH="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks"
> CMAKE_PREFIX_PATH="/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr"


doesn't help either.

I guess I have to open a ticket.

bests,
 Samuel
