function Copy-PSCI {
    <#
    .SYNOPSIS
    Copies PSCI library with specified modules and external libraries.
 
    .DESCRIPTION
    Not all DSC modules will be included - only these that are actually used in configuration files will be copied.
 
    .PARAMETER OutputPathPsci
    Output path where PSCI will be copied to.
 
    .PARAMETER ModulesToInclude
    List of PSCI modules to include. If empty, only 'PSCI.deploy' module will be included.
 
    .PARAMETER ExternalLibsToInclude
    List of external libraries from to include (will be copied from 'externalLibs' folder).
 
    .EXAMPLE
    Copy-PSCI -OutputPathPsci $OutputPathPsci `
              -ModulesToInclude $ModulesToInclude `
