I have the following CMakeLists.txt:
cmake_minimum_required (VERSION 2.8.7) project (Test) set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/") find_package(CURL REQUIRED) find_package(PortAudio REQUIRED) find_package(LibSndFile REQUIRED) include_directories(src/audio src/web) set(LIBS ${LIBS} ${LIBSNDFILE_LIBRARY} ${PORTAUDIO_LIBRARIES} ${CURL_LIBRARIES}) file(GLOB_RECURSE sources ${PROJECT_SOURCE_DIR}/src/*.c) add_executable(Test ${sources}) target_link_libraries(Test ${LIBS}) Here is what my folder structure looks like:
Test/ ├── .gitignore ├── README ├── CMakeLists.txt ├── src/ │ ├── audio/ │ │ └── ... │ ├── web/ │ │ └── ... │ └── ... ├── build/ └── cmake/ ├── FindLibSndFile.cmake └── FindPortaudio.cmake When I go to compile my program on a Mac, I go into the build/ directory and run cmake .., to which the program generates:
-- The C compiler identification is Clang 5.1.0 -- The CXX compiler identification is Clang 5.1.0 -- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -- Check for working C compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ -- Check for working CXX compiler: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Found CURL: /usr/lib/libcurl.dylib (found version "7.30.0") -- Found PkgConfig: /usr/local/bin/pkg-config (found version "0.28") -- checking for module 'portaudio-2.0' -- found portaudio-2.0, version 19 -- Found LibSndFile: /usr/local/lib/libsndfile.dylib -- Configuring done -- Generating done -- Build files have been written to: Development/Test/build Everything runs fine and dandy. But when I copy the source over to my Raspberry Pi and repeat the above steps, it spits this out at me:

Could not find a package configuration file provided by "PortAudio" with any of the following names: PortAudioConfig.cmake portaudio-config.cmake Add the installation prefix of "PortAudio" to CMAKE_PREFIX_PATH or set "PortAudio_DIR" to a directory containing one of the above files. If "PortAudio" provides a separate development package or SDK, be sure it has been installed. -- Configuring incomplete, errors occurred! I'm not too sure why it isn't working. Any suggestions?
