This is not a change to CMake. The PROJECT command has always
changed<br>
the PROJECT_NAME from that point down. My question is why
does the<br>
sub project care if it is part of a larger project or not?
For example,<br>
the jpeg library in VTK is a PROJECT(VTKJPEG), and can be compiled by
itself, but<br>
also can be part of VTK. <br>
<br>
If you want the sub project to know it is part of a larger project, then
set <br>
a variable in the cmakelist file above the sub project,
PART_OF_PROJECT xxx,<br>
then check for that in your sub project. <br>
