# PKG_INSTALL_DIR might need to be edited.  Right now it is set
# assuming that a user ran pkgconf.tcl in /cygdrive/c/ecos-work on Windows NT,
# or used the Configuration Tool with C:\ecos-work as a build-tree.
#
# You can also override it on the make command-line, e.g.:
#   make PKG_INSTALL_DIR=/myecc/install
# or you can set it in your environment
