#
|
|
# Builds a debug version:
|
|
# cmake .
|
|
# cmake --build .
|
|
#
|
|
# Builds a release version with clang
|
|
# CC=/usr/bin/clang CXX=/usr/bin/clang++ cmake -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles" .
|
|
# cmake --build .

|
#
|
|
# Builds an android armeabi-v7a debug version:
|
|
# cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake -DANDROID_NDK=$ANDROID_NDK \
|

|
|
# Todo
