Build HIDAPI

$ git clone git://github.com/Dashlane/hidapi.git
$ cd hidapi
// NOTE: the following line may be omitted if you want to try a different version than I used
hidapi $ git checkout b00982f
hidapi $ ./bootstrap
hidapi $ ./configure --enable-static --disable-shared
hidapi $ make clean
hidapi $ make
hidapi $ export HIDAPI_LIBS="-L`pwd`/mac/.libs/ -lhidapi"
hidapi $ export PKG_CONFIG_PATH="`pwd`/pc/"
hidapi $ echo $HIDAPI_LIBS

Install OpenOCD

Seems gross to copy the path directly, but trust me it doesn't work unless you do

Download https://sourceforge.net/projects/openocd/files/openocd/0.10.0/
$ cd openocd/openocd-0.10.0
openocd-0.10.0 $ HIDAPI_LIBS="<path_copied_before>" PKG_CONFIG_PATH="<path_copied_before>" ./configure --enable-cmsis-dap --disable-werror
e.g. openocd-0.10.0 $ HIDAPI_LIBS="-L/Users/brett/code/openocd/hidapi/mac/.libs/ -lhidapi" PKG_CONFIG_PATH="/Users/brett/code/openocd/hidapi/pc/" ./configure --enable-cmsis-dap --disable-werror
openocd-0.10.0 $ make clean
openocd-0.10.0 $ make install
// this should end with `done`

// check in a new tab
$ which openocd
/usr/local/bin/openocd
$ ls -l /usr/local/bin/openocd

@jief666 thanks, changed this:

hidapi $ export PKG_CONFIG_PATH="`pwd`/mac/pc/"

to this:

hidapi $ export PKG_CONFIG_PATH="`pwd`/pc/"

Welcome.

Suggest changing:

git clone git://github.com/Dashlane/hidapi.git

to the http endpoint:
