Hello,
I am attempting to build libpandadna on Ubuntu 18.10 using Panda3D 1.10.
At first, I tried to just compile it using the usual cmake ., but I received the following output:
$ cmake .

First thing that I notice is that it is not correctly detecting where interrogate is installed. After making the following change,

Next, I opened up the makepanda script that is used to build Panda3D and inferred the following interrogate commands by recreating the commands executed from there:
interrogate -srcdir /stuff/tt/libpandadna/src/base -DCPPPARSER -D__STDC__=1 -D__cplusplus=201103L -D__attribute__\(x\)= -D_LP64 -oc /stuff/tt/libpandadna/src/base_igate.cxx -od /stuff/tt/libpandadna/src/base.in -fnames -string -refcount -assert -python-native -S/stuff/tt/panda3d/built/include/parser-inc -I/stuff/tt/libpandadna/src/base -S/stuff/tt/panda3d/built/tmp -S/stuff/tt/panda3d/built/include -S/usr/include/eigen3 -I../components -S../components -I../suit -S../suit -module libpandadna -library base DNAStorage.h dnabase.h DNALoader.h config_dna.h
interrogate -srcdir /stuff/tt/libpandadna/src/suit -oc /stuff/tt/libpandadna/src/suit_igate.cxx -od /stuff/tt/libpandadna/src/suit.in -DCPPPARSER -D__STDC__=1 -D__cplusplus=201103L -D__attribute__\(x\)= -D_LP64 -fnames -string -refcount -assert -python-native -S/stuff/tt/panda3d/built/include/parser-inc -I/stuff/tt/libpandadna/src/base -I/stuff/tt/libpandadna/src/suit -S/stuff/tt/panda3d/built/tmp -S/stuff/tt/panda3d/built/include -S/usr/include/eigen3 -I../components -module libpandadna -library suit -Dvolatile= DNASuitPoint.h DNASuitEdge.h SuitLeg.h SuitLegList.h DNASuitPath.h

After executing each command in the appropriate folder src/base, src/suit and src/components, each completed successfully and created their respective output files:
$ ls
base components run_interrogate.py suit.in
base_igate.cxx components_igate.cxx suit
base.in components.in suit_igate.cxx
Then I commented out the following 2 lines in run_interrogate.py in order to get the final interrogate_module command to run:
#for module in ('base', 'suit', 'components'):
# interrogate(module)
After that, cmake . worked perfectly. Finally, I had to make a few other changes to the CMakeLists.txt to get it to see p3interrogatedb (I also had to get it to use Python 2, but that can be ignored):

Finally after all these actions, I was able to build libpandadna and successfully ran the tests.
I am sure many of these things should be generalized, which is why I am not going to simply submit a pull request at this point.
For example, the linking part of the panda3d problems can possibly be solved by actually using the find_library output. I am not much of a CMake buff so some of this stuff is not "my thing".
I just want to share my experience in case it will help others.
