Ok, fixed but it's really a PITA to have to type -DCMAKE_TOOLCHAIN_FILE=..
so often when 100% of the people on this project are cross-compiling.
And I'm still being bit by differences between Fedora and Ubuntu...
Compiling is working fine again on Fedora but on Ubuntu it's failing to
find the STM32 library. 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):

Thanks,
