Master branch can't find ladspa effects

[Umcaruje]

In the master branch, LMMS does not seem to find any of the ladspa effects that come shipped with it. It finds all my external ladspa's from the hard-coded places fine (/usr/lib/ladspa and ~/ladspa).

I suspect that this has something to do with #1908, since that was the only major thing that has changed about the ladspa paths that I can think of.

I also can't seem to change my ladspa paths in the settings dialog. They seem to reset to their default value whenever I restart LMMS.

I have similar issues. In my case, my ladspa path in the settings dialog looks like /usr/local/bin/../lib//ladspa/,/home/colin/lmms/plugins/ladspa/, and I cannot modify it. The double slash looks indicative of a possible error somewhere. Indeed, if I symlink /usr/local/lib/ladspa to /usr/local/lib/lmms/ladspa, then LMMS can properly find the effects.

I'm thinking ConfigManager.cpp:380 is in part to blame for this incorrect default path. The line looks like:

m_ladDir = qApp->applicationDirPath() + '/' + LIB_DIR + "/ladspa/";

and is #if'd in order to only run on Linux. For apple, we have

m_ladDir = qApp->applicationDirPath() + "/../lib/lmms/ladspa/";

It's hard for me to trace back the definition of LIB_DIR completely, but it appears to be calculated on DetectMachine.cmake:40 and then sent into the compiler on CmakeLists.txt:41

On @Umcaruje your 1.1.3.01.07.15 binary Master, i have noticed that it takes ~ 3-5 times longer, to open the FX-collection (both on mixer fx-tab, and on preset-fx-tab) , compared to time on the 1.1.3 -Could the prolonged time be related to this?
