This commit attempts to use a more cmake-friendly approach when
handling inter-target dependencies. A combination of macros and
include_directories usage provided overzealous compile -I/blah
entries which equates to large catch-all build commands. For
example, the last CXX target contains include directories for nearly
all preceeding targets (~190). Library dependencies were also often
wrong or missing.
* Removed nearly all used of include_directories (swig cmake
commands still appear to need these for generating the swig
command line)
* Updated usage of target_link_libraries in upm_module_init,
also changed to using target_include_directories per target.
This greatly simplifies upm/mixed_module_init usage for libraries
which depend on other libraries (in this project).
example (src/tb7300/CMakeLists.txt)
old:
# upm-libbacnetmstp will bring in libbacnet, I hope
set (reqlibname "upm-bacnetmstp")
include_directories(${BACNET_INCLUDE_DIRS})
include_directories("../bacnetmstp")
upm_module_init()
upm_target_link_libraries(${libname} bacnetmstp)
new:
upm_module_init(bacnetmstp)
The reason here, is that tb7300 depends on bacnetmstp, which
depends on BACNET includes/libs, so tb7300 gets the headers and
libraries transitively via its dependency on bacnetmstp.
* Updated pkg-config .pc file generation flow to reflect changes
with dependencies.
* Create a real target for the interfaces (CXX abstract sensor
classes). Renamed the directory from 'upm/src/upm' to
'upm/src/interfaces' Also changed the install location of the
interface headers to include/upm/interfaces. Updated interface
header usage to reflect this.
* Updated a few sensor libs to use fwd declarations for mraa.
Ideally the UPM libs would do more of this which eases the
burden on anyone building on top of the sensor libraries since
they would not need to know about mraa headers.
* Fixed examples which use symbols not defined in local includes
