I quite clearly specify its in the BINARY directory but on Ubuntu it's still looking for it in the SOURCE directory... set(PERIPHLIBVER 1.8.0) set(PERIPHLIBNAME STM32F4xx_DSP_StdPeriph_Lib_V) set(PERIPHLIBDIR ${CMAKE_BINARY_DIR}/${PERIPHLIBNAME}${PERIPHLIBVER}) set(CMSIS ${PERIPHLIBDIR}/Libraries/CMSIS) set(STM32F4LIB ${PERIPHLIBDIR}/Libraries/STM32F4xx_StdPeriph_Driver) set(STM32F4TEMPLATE ${PERIPHLIBDIR}/Project/STM32F4xx_StdPeriph_Templates) set(DSPLIB ${PERIPHLIBDIR}/Libraries/CMSIS/DSP_Lib) Output on Ubuntu: cmake -DCMAKE_TOOLCHAIN_FILE=STM32_Toolchain.cmake ~/svn/freetel/codec2-dev/stm32/-- Configuring done CMake Error at CMakeLists.txt:134 (add_executable): Cannot find source file: /home/richard/svn/freetel/codec2-dev/stm32/STM32F4xx_DSP_StdPeriph_Lib_V1.8.0/Libraries/CMSIS/DSP_Lib/Examples/arm_fft_bin_example/GCC/arm_fft_bin_data.c Thanks, Richard
