installation instructions do not mention tar.exe is required on a PATH

Describe the bug Alternative installation instructions fail to mention requirement that tar.exe capable of handling bzip content is on the path, e.g. libarchive's bsdtar with a link from bsdtar.exe to tar.exe since CMakeLists.txt hardcodes the tar executable name as tar without an opportunity to specify or discover alternative executable names.

To Reproduce Use Windows 2012 R2 x64 (Microsoft Windows [Version 6.3.9600]). Install Visual C++ redistributable 2013 x64. Install SAP NW RFC SDK 7.50 (750 Patch Level 8). Install node.js LTS 14 (14.17.3) along with tooling. Set SAPNWRFC_HOME=c:\nwrfcsdk. Add c:\nwrfcsdk\lib to the PATH. Check that rfcexec (c:\nwrfcsdk\bin\rfcexec.exe) runs without errors. Install Visual Studio 2019 for C++ build. Follow the alternative installation instructions (git clone, npm install, npm run addon). Build errors out with "file RENAME failed to rename" on line 69 of CMakeLists.txt which attempts to rename folder created by tar command on line 67: execute_process(COMMAND tar -xzf ${NODE_HEADERS_DOWNLD_PATH}).

Screenshots The following is the transcript showing the error on a system without tar.exe in the path:

Environment

The output of node -p "require('node-rfc').environment" is not available because module won't install

Additional context Certain Windows 10 builds ship with libarchive's bsdtar implementation in C:\Windows\System32\tar.exe - see Microsoft blog post ; or download your own copy from libarchive. Once downloaded, add it's bin to path and use mklink to link bsdtar.exe as tar.exe.
