Normal Usage:

$ git clone --recursive https://github.com/changyy/nginx-cmake.git
$ cd nginx-cmake
$ mkdir build
$ cd build
$ cmake ..
$ make
$ ./nginx-out/sbin/nginx -p ./nginx-out/

Cross Compiler (Testing on ARM Device):

$ git clone --recursive https://github.com/changyy/nginx-cmake.git
$ cd nginx-cmake
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=/path/toolchain-arm6.cmake
...
CMake Error at CMakeLists.txt:14 (message):
  Please use -DREMOTE_DEVICE_SSH_LOGIN='account@remote_device_ip' again (need
  sshd & scp service)
...
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=/path/toolchain-arm6.cmake -DREMOTE_DEVICE_SSH_LOGIN='[email protected]'
$ make
$ scp -r ./nginx-out [email protected]:/tmp
$ ssh [email protected] "/tmp/nginx-out/sbin/nginx -p /tmp/nginx-out/"
(need to check the shared library used by sbin/nginx: readelf -a sbin/nginx | grep Shared)
