cmake goes into infinite loop

After loading working CMakeLists.txt everything works as expected. Then in my project list I select CMakeLists.txt to make some edits.
I got this few times that if I have error in CMakeLists.txt and save Qt Creator automatically runs cmake on it. That is fine but one some errors from my best recollection it does into infinite loop. Error, cmake, Error, etc
There is no "Stop" button. So the only way to do this is to fix the error or comment the offending line and save. Then it stops.

Here is first error and the last line where it auto restarts and then errors in loop

CMake Error at CMakeLists.txt:538 (set):
Syntax error in cmake code at

/home/rob/projects/apkLib/CMakeLists.txt:539

when parsing string

${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm;${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm

Invalid character (';') in a variable name:
'CMAKE_CURRENT_SOURCE_DIR/prerm'
