Brad, All,

On 2018-08-23 15:20 -0500, Brad Love spake thusly:
> When the dynamic/static library of i2c-tools is enabled it is installed
> to the target destination. However, in order for external packages to
> link against it, it must also be installed to staging.
> 
> Here, the flag is set to install the package to staging. The
> INSTALL_STAGING command is included to only install the library
> and header file in order to utilize libi2c externally. The make
> targets are used for the installation to accomodate whether static
> or dynamic library was selected during configuration.

I guess that 'make install' also installs the lib and headers, right? If
so, I'd prefer we use that; it is not a problem that programs are also
instaleld in staging.
