i'm build folly but cannot find FBBuildOptions

[oska874]

When I build lastest folly, I face the error below, how to get FBBuildOptions and fb_activate_static_library_option ?

$ ./folly/build/build-debs-ubuntu-18.04.sh

Did you run the following, before executing build-deps? I used to have a few build errors, too, but installing the required dependencies solved them.

sudo apt-get install \
    g++ \
    cmake \
    libboost-all-dev \
    libevent-dev \
    libdouble-conversion-dev \
    libgoogle-glog-dev \
    libgflags-dev \
    libiberty-dev \
    liblz4-dev \
    liblzma-dev \
    libsnappy-dev \
    make \
    zlib1g-dev \
    binutils-dev \
    libjemalloc-dev \
    libssl-dev \
    pkg-config \
    libunwind-dev

I met the same problem because I remove build folder........ In folly, build folder is not designed for cmake build....

Also not found FBBuildOptions symbol in the project. Exception is the include in root CMakeLists.txt.

Trying to build CMake in according with guide (README.md).
