cva: TS2742 - inferred type cannot be named without a reference

Describe the bug The following TS error is encountered when attempting to build a library with class-variance-authority@0.6.0:

The inferred type of 'someCVAVariable' cannot be named without a reference to '../../../node_modules/class-variance-authority/dist/types'. This is likely not portable. A type annotation is necessary.ts(2742)

Similar to issue: https://github.com/joe-bell/cva/issues/27

TypeScript version: 5.0.4

To Reproduce Steps to reproduce the behavior:

1. Use TSConfig with declaration: true setting.
2. Create an export utility that uses VariantProps and calls a declared cva() function. See screenshot.

Expected behavior No TS Error.

Screenshots

TypeScript Version 5.0.4

Additional context The problem is that ClassProp, ClassValue, OmitUndefined, StringToBoolean types are not ultimately exported from the class-variance-authority library. If you look at the index.d.ts file you can see those types are imported and referenced in other types, but they ultimately aren’t exported themselves (see the last line in of index.d.ts of export {}.

Simply exporting those types fixes the issue.

ie

diff --git a/dist/index.d.ts b/dist/index.d.ts

Happy to submit a PR.
