Note the order above.
Also, cmake variables are ALWAYS used with braces ${Variable} NOT
$Variable.

Thanks for that, Mike :-)
The sample code corresponds to what I'm doing, even the order
happens to be the same. I still keep getting GTK include errors.
Tried include_directories (... ${GTK_INCLUDE_DIR}) in all orders.
BTW: Why does the order matter ? How do I know the right order ?
When I use hand-coded include paths, I get GTK linker errors.

True,there is nothing GTK-related in the compile line.
So does FindGTK silently fail to find GTK inc/libs ?
If so, how can I fix that ?
You need to "add_executable" before you can "target_link_libraries".
The add_executable command adds a "target" called myexec. Then you
"target_link_libraries". Think of the "add_executable" as the compile
step and the "target_link_libraries" as the link step. You have to
compile before you can link. ;-)
Looking at the FindGTK module in CMake 2.6.1 it would seem that it
will silently fail. add the following to your cmake code:
FIND_PACKAGE(GTK REQUIRED)
IF (NOT GTK_FOUND)
MESSAGE (FATAL_ERROR "GTK NOT FOUND")
ENDIF (NOT GTK_FOUND)
then your add_executable and target_link_libraries lines and lets see
what happens
