CMake process broken when CMAKE_INSTALL_PREFIX is defined

[Stefan Ritt]

Following commands break in my case:

‌

$ cmake -DCMAKE_INSTALL_PREFIX=/some/path ..
$ make
...
[ 32%] Building CXX object manalyzer/CMakeFiles/manalyzer.dir/manalyzer.cxx.o
/midas/progs/mlogger.cxx:14:10: fatal error: 'midas.h' file not found
#include "midas.h"
         ^~~~~~~~~
...

‌

confirmed. everything under “progs” cannot find midas.h & co.

‌

daq00:midas$ mkdir xbuild
daq00:midas$ cd xbuild/
daq00:xbuild$ cmake .. -DCMAKE_INSTALL_PREFIX=/some/path
...
daq00:xbuild$ make -j
... bombs!

it takes me 7 days to fix any minor cmake problem and then 7 days of swearing at people who invented cmake and imposed it on the world. what a piece of junk.

[Stefan Ritt]

Why don’t you keep your fingers off cmake and simply use and maintain your old make, and leave the cmake business to other people.

[Stefan Ritt]

Finally had some time to look into that. Fixed by adding missing include files like

target_include_directories(midas PUBLIC $<BUILD_INTERFACE:${BUILD_INC_DIR}>)

Now midas compiles even if cmake is called with -DCMAKE_INSTALL_PREFIX=...
