You are adding an executable without files, so CMake can't determine which
language (C or C++) to use. You do

> set( SOURCES src/ptedit_1.cpp )

but then

> kde4_add_executable( ptedit_1 ${ptedit_1Sources}  ${CMAKE_SOURCE_DIR})

Adding the source dir there is totally wrong, and ptedit_1Sources has
never been set before.

Since I see you struggle with this stuff for some days: put message(STATUS
"${myvar}") at different places in your CMakeLists.txt to see the contents
of the variables. Check if they make any sense. Hint: myvar is again a
placeholder.

Take a working project (KDE has many of them) and modify the
CMakeLists.txt to fit your need, i.e. replace the values of the variables
with your files.
